以某型直升机尾减速器弧齿锥齿轮传动系统为对象，建立该齿轮传动系统温度场仿真计算模型，计算获得在正常润滑条件下该齿轮传动系统的稳态温度场。基于当量齿轮原理，将弧齿锥齿轮副等效为法面当量直齿圆柱齿轮副，其啮合侧隙将直接反映在法面当量直齿圆柱齿轮副的端面上。利用热弹性力学原理，计算分析了正常润滑条件下传动系统的热变形对弧齿锥齿轮副啮合侧隙的影响，并得到了相关结论。为考虑热变形时正确确定弧齿锥齿轮副侧隙、保证工作精度，提供了理论依据。

Taking the spiral bevel gear transmission system of a helicopter tail reducer as research object,a computation model for the temperature field simulation was built,a steady-state temperature field distribution was derived under normal lubrication condition.The spiral bevel gear can be equivalent to the spur gear in basis in equivalent gear theory,and its gear backlash can be reflected at the transverse plane of the equivalent spur gear .The influence of thermal deformation of the spiral bevel gear transmission system on the gear backlash was computed and analyzed under normal lubrication condition using the thermo-elasticity theory.The results provided a theoretical basis for the design correctness of backlash considering thermal deformation,thus ensuring the working accuracy of the spiral bevel gear.
